1 Claim.

The present invention relates to stoves, and has for its main object the provision of a stove made Vof a number of parts Which may be readily assembled or disassembled.

`A still further object of the present invention is the provision of a stove with increased radial surface so as to obtain therefrom a maximum of heating eficiencies.

i With the above general objects in view and others that Vwill appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described and illus-` trated in the accompanying drawing and pointed out in the appended claim.

In the drawing formingva part of this application, and in whichA like designating characters refer to corresponding parts throughout the sevview, partly in sec- Fig. 4 is a perspective view of one of the baffle` elements used in connection with the stove; and

Fig. 5 is an enlarged horizontal cross-sectional view through the corner of a stove.

Referring in detail to the present drawing, the stove includes an ash box l0, including bottom Wall I l and four vertical side Walls I2, integrally formed With said bottom wall l I. Provided in the front vertical Wall l2 is door I 3, the latter provided With a plurality of Conventional slots l4 With a slidable plate in the rear thereof for the purpose of regulating the draft. Said door l3 afords access to said ash box l for the purpose of removing ashes therefrom,

Ash -box |0 is supported upon legs I5, one at each corner of the stove. The upper ends of said legs |5 are slotted for receiving therewithin in a frictional relation angle irons [6, Which extend upwardly and above said ash -box l0.

The upper ends of vertical walls l 2 are grooved for providing a seat for the marginal edge of plate flange 11, from which a pair of upwardly tapering side walls 18, and a pair of straight end Walls l9 project. Said Walls IB and I9 are integrally formed with said plate flange I 1 for defining a fire box 20. All of said Walls IB and I9 are spaced from the continuation planes of said vertical walls |2 of ash box l0. The bottom of said fire box is open for receiving grate 2I upon which fuel is adapted to burn and through Which ashes are adapted to fall into the ash box I0. The front end wall 19 is provided with door 22 through which access is afforded into said fire'box 20. f The upper ends of walls |8 and |9 are grooved for receiving a top Wall 23, which completes the structure of said fire box 20.

Said-'top Wall 23 -has a plurality of annular openings 24, each of which is adapted to receive collar 25, projecting above said top Wall 23.

Cooperating with each of said collars 25 isa funnel-shaped baflie element 26, having at'its upperv wider end a plurality of arms 21 integrally vformed with and laterally projecting therefrom. Said baflie elements 26 are recivable Within `upper ends of collars 25, With arms 21 resting upon upper ends of said collars 25. The diameter of each of said bafiie elements 26 is shorter than the diameter of saidcollars 25 so that when said baffle elements 26 are in an operative poslav tion with relation to said collars 25, the upper ends of said baflle elements 26 with the adjacent inner periphery of said collars 25 define annular slots 28, through Which smoke and combustion gases are adapted to pass from said fire box 20 and above collars 25. The function of said baffle elements 26 is to retard the escape of smoke and combustion gases from fire box 20 so that the same may be more thoroughly consumed While still therewithin.

The stove further includes a plurality of flues 29, the lower ends of which are annular and the upper ends of Which are flattened to define an elliptical formation on horizontal cross-section. The lower ends of said flues 29 are positioned over said collars 2'5 and frictionally engage .the latter over their outer peripheries as is clearly seen in Fig. 1.

Positioned over said flues 29 and supported thereby is dome 35! which has a straight bottom wall 3! and a pair of end Walls 32 and an arcuate roof Wall 33. Made in said bottom Wall 31 is a plurality of oblong or elliptical openings 34, from the margins of which sleeves 35 of like formation downwardly project, said sleeves 35 being integrally formed with said bottom Wall 3l. Engaging the outer peripheries of said sleeves 35 are the upper elliptical ends of said flues 29.

Seated upon the ends of vertical Walls I2 and on the same plane therewith are four walls 36 of hood 31 enclosing fire box 20, flues 29 and dome 30. Top wall 38, positioned upon the upper ends of walls 36, completes the structure of said hood 31.

Said walls 36 are maintained in an operative position by means of said angle irons l6, as is clearly seen in Figs. 3 and 5, and to maintain said angle irons IB a plurality of corner brackets 39 are attached to vertical walls l2 as Well as to walls 36.

It is observed that fire box 20, fiues 29 and dome 30 are all spaced from side Walls 36 and top Wall'38 of hood 31. To provide access to door 22 of fire box 20 a rectangular jamb 40 is provided, the rear end of Which connectswith the front wall F9 Vof fireibox 20, and the front end of which connects With the adjacent front wall 36 of hood 31. Said front wall 36 is correspondingly cut away for providing access to said door 22 through jamb 40.

Each of end walls 32 of dome 30 is provided With a horizontally extending pipe 41, each ex*- tending through the front or rear Wall 36 to selectively carry away smoke and combustion gases from dome 30 into the chimney flue. Oneof said pipes dl not in use may be closed by cap 42.

Made adjacent the lower ends of side walls 3'6 of hood 31 vis a plurality of openings 43, through 'Which 'air is adapted to pass into said hood 31 to be heated by the radiating fire box 2'0, flues 2'9 and 'dome 30 and to fiow in an up- Wai'd directi'oh to ultim'ately escape into the dwelling through a plurality of openings 44 made in top Wall 38 of hood 31. The inclined vside Walls |`8 of fire box 20 retard the flow of air through said openings 43 upWardly in order to facilitate a thorough absorption of heat by the ai-r When it comes in contact with said side Walls l8 and before the same escapes upwardly through spaces de'fined by the upper ends of said side walls 19 and the adjacent side walls 36 of hood 31.

From the hereinabove description -it Will be apparent that the stove herein disclosed is made of .plurality of parts which are capable of quick assembly and disassembly, and that the same has a large area exposed of the parts through Which fiame and combustion gases come in contact, Whereby the greatest degree of radiation is brought about for the purpose of enhancing the efficiency of the stove.

It is further observed that a number of flues 29 may be vared, either decreased or increased, depending upon the size of the stove and its capacity. Some of said flues 29 may be entirely eliminated and a lesser number thereof used, sufficient however to support 'dome 30. Collars 25 and sleeves 35 in those flues 29 Which are eliminated, may be capped preventing escape of combustion gases through those in connection with 'Which flues 29 are not in use.

While there is described herein a preferred embodiment of the present invention, it is neverthele'ss -to be understood that minor changes may be made therein Without departing from the spirit and scope of the invention as claimed.

What -I `claim as new is:

In a stove 'comprisin'g a fire box including a top wall thereof, -a plurality `of openings made in said top Wall, a collar seated within each of said openings, fiues each connecting by its lower end with vone of said collars, a dome overlying the upper ends of said fiues and supported there'- by, said dome having a plurality of openings, and a sleeve extending and downwardly depending from the marginal edge of each of said openings, said sleeves being receivable by the upper ends of said flues: that improvement comprising inverted conical baflle members positioned within said collars, said baflle members having lateral extensons engaging the upper ends of said collars, the combustion gases being adapted to pass from said fire box into said flues through said collars and past said ba-flle members and into said dome through said sleeves.
